The LNCMI conducts extensive developments of cryogenic devices and scientific instrumentation compliant with the particular constraints of resistive high field magnets. The technical challenges comprise very low (20 mK) or very high (1000 \u00b0C) temperatures, limited sample space, mechanical and electrical noise, vacuum, high pressure, in-situ sample rotation, spatially resolved optical spectroscopy, high frequency circuits for nuclear magnetic resonance and compatibility with neutron, x-ray or intense laser beam lines.<\/span><\/p>\n

As high field magnets are different from any “standard” laboratory magnet, the LNCMI designs, constructs, operates and refines tailored cryogenic devices like 4<\/sup>He and 3<\/sup>He cryostats or 3<\/sup>He\/4<\/sup>He dilution refrigerators. LNCMI also provides a thermometry platform for thermometer calibration at cryogenic temperatures (actually down to 1.2 K) under high magnetic fields (up to 36 T).<\/span><\/p>\n

Moreover, the LNCMI continuously develops and improves experimental techniques like thermoelectric power and contactless resistance (TDO) measurements, resolution enhanced devices for optical spectroscopy, high resolution NMR, magneto-hydrodynamics and many others.<\/span><\/p>\n

The development of new techniques and devices is realized in close collaboration between the researchers and the cryogenics and scientific instrumentation team with support from the design office, the mechanical workshop and the electronics laboratory. The scientific instrumentation team is composed of specialists in mechanics, cryogenics, CAD design, electronics, optics, programming and general scientific instrumentation.<\/span><\/p>\n
